Electrical Energy Storage Technologies and Applications

This book focuses on the energy storage system and their application technologies, consolidating the author's theoretical accumulation and practical experience in power energy storage, distributed generation, microgrids, and smart grids in recent years. It is divided into three parts. The first part is an overview, which first focuses on the revolutionary development of the power system and analyzes the role of energy storage in power system frequency regulation, peak shaving, renewable energy integration and microgrids; followed with the introduction of typical energy storage technologies including their current technical principles, development and application trends. The second part focuses on the system composition, grid access topology and control technology of battery and flywheel energy storage; then, the theoretical basis and control methods of hybrid energy storage system with energy-type and power-type of subsystem are analyzed, as well as energy storage big data analysis methods and applications for optimized operation. The third part analyzes the dual mode operation and peer-to-peer control method of microgrid based on energy storage, the method of applying energy storage to the fluctuation suppression and improvement of frequency and voltage regulation characteristics of renewable energy generation, and the optimal dispatching method of virtual power plant including energy storage and distributed generation. This book aims to build a bridge between energy storage and power system applications from the sight of future development of power system. It is suitable for undergraduate students, graduate students and engineers with a certain level of professional knowledge in energy storage systems, power systems, etc. The basis of English translation of this book, originally in Chinese, was facilitated by artificial intelligence. The content was later revised by the authors for accuracy.
